Beer for washing hair
啤酒是洗头用的

Two nuns were shopping and happened to be passing the beer store.  One asks the other if she would like a beer. The other nun answered that would be good, but that she would be queasy about purchasing it.  The first nun said that she would handle it and picked up a six pack and took it to the cashier. The cashier had a surprised look and the first nun said, "The beer is used for washing our hair."  The cashier, without blinking an eye, reached under the counter and put a package of pretzels in the bag with the beer, saying. . ."Here, don't forget the curlers."

两个修女外出购物，路过一家啤酒店。 其中一个修女问另外一个要不要买点啤酒喝。 那个修女回答说她是想喝，但不太敢去买。 第一个修女说她会搞定，说罢拿起一提六瓶装的啤酒，来到收银台。 看到收银员的表情有点怪，第一个修女说，“我们买啤酒是用来洗头的。” 收银员，眼皮都没有眨一下，把手伸进柜台下面，拿出一包椒盐饼干放到装啤酒的袋子里面，说“嘿，卷发器可不能少!”
